FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 417,125, datedDecember 10, 1889.

Application filed April 1, 1889- To aZZ whom it may concern:

Be it known that I, RICHARD \VALsH, a citizen of the United States,residing at Detroit, in the county of lVayne and State of Michigan, haveinvented certain new and useful Improvements in Flushing Apparatus forWater-Closets, of which the following is a specification, referencebeing had therein to the accompanying drawin This invention relates tonew and useful improvements in flu shin g apparatus for waterclosets;and the invention consists in the peculiar construction, arrangement,and combinations of parts hereinafter more fully described, shown in thedrawings, and then definitely pointed out in the claims.

Figure 1 is a sectional elevation of a watercloset provided with myimprovement. Fig. 2 is a plan. Fig. 3 is a vertical central section ofthe flushing-valve, and Fig. l is a horizontal section of theflushing-valve.

A is a bowl.

B is a hinged seat.

C is a hinged frame underneath the seat.

D are vertical pushbars secured to the hinged frame and projectingthrough the stationary seat of the frame against the under side of thehinged seat, whereby they are adapted to hold the latterin apartially-raised position.

E is a flushing-valve, divided by an interior partition F into aninduction-chamber G and eduction-chamber H.

I and J are the induction and cduction ports of the valve in axial linewith each other, the port I being formed in the interior partition F,and the port .l in the outer wall between the connection K of theservice-pipe and the valve-chamber G. The valve-chamber G communicatesthrough the connection K with the service-pipe L, attached thereto, andthrough the connection M with the Hushing pipe N, which extends upvertically into the flushingtank O and terminates therein into a siphonP. The valvech'amber H is provided with a suitable connection Q, bymeans of which the valve is attached to the nipple R of the bowl, andwith a connection S, to which the flushing-pipe T is secured, whichextends upwardly into the fiushing-tanlc O and terminates into a shortsiphon U.

V is the valve-stem of the flushing-valve Serial No. 305,594. (Nomodel.)

projecting through a nipple W on the valvecasing. This nipple isinteriorly provided with a packing around the valve-stem and ex- Iunderneath the hinged frame 0. The valvestem is provided with avalve-disk Z, which controls the port I, and with a valve-disk Z, whichcontrols the port J, the latter valvedisk being preferably made ofelastic rubber to be seated tightly When closed.

The flushing-valve,besides being supported byits connection with thenipple of the bowl, is supported upon the leg A, which adjustablyengages into a foot A, secured upon the floor.

It will be observed that by my peculiar arrangement of the valve,whereby the siphonoverflow passes from the tank through thefiushingwalve, only a single double-acting valve is required, instead oftwo separate valves, as has been proposed, and the valve mechanism istherefore much simplified.

In practice, the parts constructed and arranged as shown and described,are intended to operate as follows: hen the seat is notoccupied, theweight Y causes the lever Y to lift the hinged frame, whereby thepush-bars D hold the seat in an uplifted position, as shown in Fig. 1,suitable nuts or collars D being secured upon the push-bars as stops. Inthis position of the lever the stem V of the valve is fully pushed intothe valve and closes the port J, which connects it with the supply andopens the port 1. Upon the seat being occupied the push-bars aredepressed and cause the levers to turn the valvestem, which latter issimultaneously withdrawn by the screw-thread engagement of the nut \V onthe nipple WV. This movement is sufficient to close the port I and openthe port J. Thus water is admitted into the chamber G of the valve, andfrom there, by the pressure of the water, it is carried up through theflushing-pipe N and siphon P into the tank 0, filling the latter. Now,as the water raises in the tank above its ordinary height it will beginto overflow through the siphon U into the pipe, and from there throughthe pipe H in the valve into the bowl. This overflow starts the siphon,and a copious rush of water, orso-called fore-flush, will take placethrough the pipe T into the bowl until the level of the water sinks tothe level of the siphon U. The siphon U preferably extends only a littledistance toward the bottom of the tank, but enough, provided the tank issufficiently large, to form a sufficiently-copious overflow or flush towet the interior of the bowl, and as water flows into the tank rightalong, if the seat is occupied long enough, a periodical fore-flush oroverflow will take place from time to time. Upon leaving the seat theweight Y is caused to actuate the valve-stem to close the port J andopen the port I.- This shuts ott the pressure of the Water and at thesame time opens communication from the flushing-pipe N, through the portI, chamber II, and connection Q, into the bowl, allowing the water inthe flushing-pipe to escape into the bowl and thereby start the siphon Ithus producing the ordinary after-flush.

It is obvious that the amount of fore-flush should be limited to retainenough water in the tank to produce at any moment a sufficientafterwash, and to this end the siphon U extends only a little distancebelow the highest level of the Water in the tank.

WVhat I claim as my invention is 1. In a flushing apparatus, thecombination, -wltl1 the bowl, of the flushing-valve provided with theinterior partition F, forming an induction and educt-ion chamber in thevalve, the service-pipe connected to the induction-chamber through aport J, the port I between the eduction and induction chambers of thevalve, the valve-stem provided with the disks Z and Z, automaticallycontrolling the ports I and J by intermediate connection with the hingedseat, the flushing-pipe N, connecting the tank with theinduction-chamber of the valve, the overflowpipe T, connecting the tankwith the eduction-chamber of the valve, and the siphon U on the saidpipe, all combined to operate substantially as described.

2. In a flushingapparatus, the combination, with the flushing-tank andflushingvalve, of the flushing-pipe N, connecting the Valve-chamber withthe tank and having a siphon P within the tank, the pipe T, connectingthe valve-chamber with the tank, and the short-leg siphon U on said pipewithin the tank, substantially as and for the purpose specified.

3. In a flushing apparatus, the comblnation, with the flushing-tank andflushingvalve, of the flushing-pipe N, connecting the valve-chamber Withthe tank and having a siphon P within the tank, the pipe T, connectingthe valve-chamber with the tank, and the siphon U on said pipe withinthe tank and extending but slightly below the highest level of the waterin the tank, substantially as and for the purpose specified.

In testimony whereof I atfiX my signature, in presence of two witnesses,this 6th day of February, 1889.

RICHARD WALSH.
